The equation P = 2(l + w) can be used to find the perimeter P of a rectangle with length l and width w. Solve the equation for w to produce a formula for finding the width of a rectangle given its perimeter and length.


The formula is w = (blank)

Respuesta :

Answer:

w = P/2 - l

Step-by-step explanation:

P = 2(l + w)

P/2 = l + w

w = P/2 - l

Answer:

[tex]w = \frac{P}{2} - l[/tex]

Step-by-step explanation:

P = 2(l + w)

Divide 2 to both sides:

P / 2 = l + w

Minus l to both sides:

P / 2 - l = w

Rewrite the equation:

w = P/2 = l
